Segmental colonic transit has been measured in 101 patients. Two MBq of 111Indium absorbed on resin pellets and encapsulated in an enteric coated capsule was given at 7 00 am. Hourly images during the first day, and three images during each subsequent day were acquired for up to three days. Using all scan and patient data the scans were categorised in one of the five patterns of colonic transit...

OBJECTIVE: To report on the importance of intestinal parasites in patients with AIDS, showing relevant data in the medical literature, with special emphasis on epidemiology, diagnosis and treatment of enteroparasitosis, especially cryptosporidiasis, isosporiasis, microsporidiasis and strongyloidiasis. DESIGN: Narrative review.

The chemical basis of the toxic and immunogenic properties of endotoxins from enteric gramnegative bacilli has been the subject of intensive investigation. Recent methods of purification yielded biologically active preparations which were essentially free of dissociable protein and consisted of complex phosphorylated lipopolysaccharides containing firmly bound peptides (1, 2). Chemical degradat...

Viruses affect host physiology beyond causing acute disease, thereby giving rise to the concept that the virome is a component of the microbiome. However, the role of the enteric virome is understudied relative to the fast-paced research examining commensal bacteria in the intestine. In this article, I discuss our recent work on murine norovirus indicating that an animal virus in the intestine ...

The US FDA approval in April 2013 of Diclegis®, the doxylamine-pyridoxine combination for morning sickness, is a major milestone, particularly since it is indicated for use in pregnancy and the FDA has labeled it a pregnancy category A drug the strongest evidence of fetal safety. After thirty years of being orphaned from an FDA-labeled drug for the most common medical condition in pregnancy, Am...

The objective of this review was to examine the application and relative efficiency of the proprietary hand-held Laser Methane Detector (LMD) in livestock production, with a focus on opportunities and challenges in different production systems. The LMD is based on IR absorption spectroscopy, uses a semiconductor laser as a collimated excitation source and uses the second harmonic detection of w...
